The wide-band wave-absorbing properties of novel metamaterial honeycomb sandwich structure composites were studied, and the effects of wave-absorbing honeycomb height and dielectric property on the wave-absorbing properties of novel metamaterial honeycomb sandwich structure composites were analyzed. The results show that the wave-absorbing properties of metamaterial structures are improved while the honeycomb heights is increased. The matching effect of metamaterial structures and wave-absorbing honeycomb is improved firstly, and then decreased with the increase of the dielectric properties of wave-absorbing honeycomb. While ε′ is between 1.59-1.84 and ε″ is between 1.31-1.75, the matching effect is optimal. By the introduction of metamaterial structures, the average wave-absorbing properties at 1-2 GHz of novel metamaterial honeycomb sandwich structure composites are significantly improved, and the weight is greatly reduced.
